A California company called Nano Diamond Battery (NDB) is currently developing a radioactive battery that is "completely safe" for humans and will "change the world" in the future. The developer of
battery explained that this kind of battery powered by nuclear waste can sustain a spacecraft or a hospital for 28,000 years without the need to recharge or replace the battery during use.
NDB hopes to begin selling the battery to commercial partners within the next two years, including space agencies that perform long-term missions. In addition, the company is also developing a consumer version of the nuclear battery , which can be used in smart phones or electric cars, and can be used for up to ten years without charging. The company has not disclosed pricing details and said the product is still in the research and development stage.
This battery technology involves combining radioactive isotopes in nuclear waste with a paneled nanodiamond layer stacked in battery cells. The technology is based on the diamond nuclear volt battery (DNV) technology proposed by scientists from the University of Bristol in 2016.
diamond nuclear volt battery uses discarded graphite blocks to convert nuclear waste into electricity. Very small diamonds have excellent thermal conductivity and can quickly remove heat from radioactive isotopes to produce electricity. Although this output power is not large, it can last for a long, long time-maybe thousands of years. If multiple units are stacked together, the overall output power can be increased. The stacking design can improve the overall efficiency of the system and provide multiple layers of security protection.This low-power battery is especially perfect for devices that consume low power but need to be powered for a long time.
NDB system can increase the total energy output by adding diamond layers and radioactive waste plates, which can be applied to consumer products. The company's CEO Nima Golsharifi said that this battery has two different advantages. One is that it can make use of nuclear waste, and the other is that it runs much longer than current batteries. At the same time, NDB is also working hard to ensure that this battery material is sufficiently safe. In use, people will not easily touch the radioactive material inside the battery unit.
A spokesperson for NDB called the stacked diamond nuclear volt battery and the radioactive source coated with a layer of polycrystalline diamond. Polycrystalline diamond is considered to be the material with the best thermal conductivity. This material can also control radiation inside the device, and it is also the hardest material, with a hardness 12 times that of stainless steel. This makes this product particularly strong and has excellent resistance to damage from external forces. Use cases include watches with small NDB batteries. Such watches can be passed on from generation to generation without the need to replace the battery.
In the future, nuclear batteries may also be able to power artificial satellites and provide them with enough backup energy to leave orbit at the end of their service life; or power the probe into deep space to perform a millennium exploration.
Electric cars equipped with this battery will be able to travel thousands of miles without worrying about charging problems.
NDB wrote on its website: The enthusiasm for exploring the unknown has prompted mankind to go deep into space.The latest development of space technology, the emergence of the first manned electric aircraft , has continuously increased our demand for battery systems, and the limited service life and safety of the batteries hindered all development. NDB's batteries can be used in drones, electric aircraft, space rover and bases, and at the same time have a longer activity. In the future, batteries can also be used in smartphones or laptops. Each device will contain a micro-generator. As long as the device is not broken, the power supply will be constant, and there is no need to recharge.
in-situ medical devices and implantable devices such as hearing aids and cardiac pacemakers will also benefit from this smaller size, longer battery life, and better safety performance. (Yun Lin)
